[0009] Hereinafter, each embodiment of the elevator maintenance work support system and elevator maintenance work support method of the present invention will be described in detail with reference to the drawings. The elevator maintenance work support system and elevator maintenance work support method described here are a system and method for supporting the safety of workers in maintenance and inspection work performed on elevator cars. In each embodiment described below, the same components are assigned the same reference numerals, and duplicate explanations will be omitted.

[0010] First Embodiment Fig. 1 is an overall configuration diagram of a maintenance work support system for an elevator 100 according to an embodiment. Fig. 2 is a block diagram of the elevator maintenance work support system 1 according to the first embodiment. First, before explaining the configuration of the maintenance work support system 1 of the first embodiment, the equipment of a worker [W] who performs maintenance work on the elevator 100 will be explained based on Fig. 1.

[0011] <Worker [W] Equipment> A worker [W] performing work on the car of elevator 100 is required to wear a safety belt 2 and a helmet 3. The safety belt 2 is a full harness-type fall prevention device, with a safety belt hook 2a attached to the end of a rope extending from the back side of the shoulder belt. The safety belt hook 2a is a fastening device connected to the safety belt 2 via a rope. This safety belt hook 2a is used at the work site by fastening to a fastening point provided at the work site, and at other times by fastening to the chest belt of the safety belt 2.

[0012] Furthermore, the work site for the maintenance work on the elevator 100 is above the car 10 of the elevator 100, in a dark environment inside the hoistway 100a through which the car 10 travels. For this reason, the worker [W] holds the light 3a attached to the helmet 3.

[0013] <System configuration> Next, the configuration of the elevator maintenance work support system 1 according to the first embodiment shown in Fig. 2 will be described with reference to Fig. 1. The elevator maintenance work support system 1 is composed of an elevator 100, a remote monitoring device 200, and a mobile terminal device 300. These are as follows.

[0014] [Elevator 100] The elevator 100 has a car 10. The car 10 is suspended by a main rope 11 in a hoistway 100a that extends vertically along the building. The car 10 is equipped with a car door 12 for entering the car. Inside the car 10, an alarm unit 13 equipped with a display unit and a speaker, an in-car switch (not shown here), and a destination floor registration unit are installed. In addition, an on-gauge switch 14 and a handrail that serves as a locking unit 15 for locking a safety belt hook 2a are installed at the top of the car 10. Furthermore, a load sensor 16 for detecting the load inside the car 10 is installed at the bottom of the car 10.

[0015] Furthermore, landing doors 17 are provided on the wall of the elevator shaft 100a facing each landing 100f. The landing doors 17 engage with the car doors 12 when the car 10 arrives at each landing 100f, and open and close in response to the opening and closing drive of the car doors 12. Further, near each landing 100f, there are provided a landing door opening / closing detection unit 18 for detecting the opening and closing of the landing doors 17, an operation unit 19 for performing various operations, and a landing call registration unit (not shown here).

[0016] The elevator 100 also has a control device 101 for controlling the driving of a hoist (not shown) around which the main rope 11 is wound, and the driving of the car door 12. The control device 101 is configured by a computer. The computer is a so-called computer hardware that includes a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and other non-volatile storage units, as well as a network interface.

[0017] The control device 101 of the elevator 100 controls the operation of the above-mentioned hoist and car doors 12 based on signals from the on-gauge switch 14, the load sensor 16, the hall door open / close detection unit 18, the operation unit 19, and an in-car switch, a destination floor registration unit, and a hall call registration unit, all of which are not shown here. Such control device 101 includes an operation control unit 102 and a setup operation control unit 103. The operation control unit 102 controls the operation of the above-mentioned hoist and car doors 12 based on signals from the destination floor registration unit and the hall call registration unit, and controls the operation of the elevator 100.

[0018] Furthermore, when performing maintenance work, the setup operation control unit 103 performs setup operation by the operation of the operation unit 19 by the worker [W], and controls the drive of the hoisting machine to place the car 10 at a predetermined height position. The predetermined height position here is a position where the worker [W] can get on the car 10 from a predetermined floor landing 100f.

[0019] [Remote monitoring device 200] The remote monitoring device 200 may be a cloud-based computer (calculator) capable of communicating with the control device 101 of the elevator 100 and the mobile terminal device 300. The remote monitoring device 200 includes an elevator / terminal linking unit 201 and an entry determination unit 202.

[0020] The elevator / terminal associating unit 201 holds data associating each elevator 100 with the mobile terminal device 300 held by the worker [W] in charge of maintenance. The elevator / terminal associating unit 201 detects that the worker [W] has entered a building having an elevator for which maintenance work is to be performed, based on a signal (registration signal) transmitted from the mobile terminal device 300. As a result, the elevator / terminal associating unit 201, by its work elevator associating function, associates and holds the mobile terminal device 300 held by the worker [W] who has entered the building with the elevator 100 for which the worker [W] is to perform maintenance work.

[0021] The boarding determination unit 202 detects the worker [W] getting on the car 16. The boarding determination unit 202 detects the boarding based on a signal from the setup operation control unit 103 of the control device 101 in the elevator 100 extracted by the elevator / terminal linking unit 201, a signal from the on-gauge switch 14, and a signal from the landing door open / close detection unit 18. The procedure for detecting boarding by the boarding determination unit 202 will be described in detail below in the maintenance work support method.

[0022] [Mobile terminal device 300] The mobile terminal device 300 is owned by the worker [W]. The mobile terminal device 300 includes an alarm issuing unit 301, an operation unit 302, an alarm issuing instruction unit 303, an alarm stop instruction unit 304, and an entry registration function 305.

[0023] The alarm unit 301 is, for example, a speaker for issuing an audio warning. A display unit for displaying a warning can also be an additional alarm unit 301. The operation unit 302 is an interface for input operations by the worker [W], and may be a display unit such as a touch panel.

[0024] The warning issuance instruction unit 303 instructs the warning issuing unit 301 to issue a warning based on a signal from the boarding determination unit 202 of the remote monitoring device 200. The warning that the warning issuance instruction unit 303 instructs to issue is a warning that prompts the user to fasten the safety belt hook 2a. The warning stop instruction unit 304 instructs the warning issuing unit 301 to stop issuing the warning based on an operation signal from the operation unit 302. Furthermore, the entry registration function 305 registers entry into the building in which the elevator 100 is installed based on an operation signal from the operation unit 302, and transmits the registration signal to the remote monitoring device 200.

[0025] <Maintenance work support method> Next, an elevator maintenance work support method implemented by the above-described elevator maintenance work support system 1 will be described. FIG. 3 is a flowchart of the elevator maintenance work support method according to the first embodiment, showing, from left to right, the actions of the worker [W], the processing procedure of the mobile terminal device 300, the processing procedure of the elevator 100, and the processing procedure of the remote monitoring device 200. Each processing procedure shown in FIG. 3 is a procedure of the elevator maintenance work support method that is executed in accordance with the actions of the worker [W] and in accordance with the programs held by each unit of the elevator maintenance work support system 1 described using FIGS. 1 and 2. The elevator maintenance work support method will be described below in the order shown in the flowchart of FIG. 3 and with reference to FIGS. 1 and 2.

[0026] [Step S01] In step S01, the worker [W] performs entry registration by operating the operation unit 302 of the mobile terminal device 300. As a result, the entry registration function 305 of the mobile terminal device 300 transmits the registration information of the worker [W] to the remote monitoring device 200 (step S101). In addition, in the remote monitoring device 200 that has received the registration information, the elevator / terminal association unit 201 associates and retains the mobile terminal device 300 owned by the worker [W] who has entered the building with the elevator 100 on which the worker [W] will perform maintenance work, using the work elevator association function (step S102). As a result, the mobile terminal device of the worker [W] is associated with one of the elevators in the building on which the worker [W] is about to perform maintenance work.

[0027] [Steps S02 to S04] In step S02, the worker [W] who has completed entry registration attaches an inspection tag to the landing door 17 of each landing 100f of the elevator 100 where maintenance is to be performed. In the next step S03, the worker [W] moves the car 10 to a predetermined floor, for example, by operating the operation unit 19. In the next step S04, the worker [W] switches the elevator operation mode to maintenance mode by operating the in-car switch inside the car 10. After switching, the worker [W] exits the car 10. The car door 12 of the elevator 100 then closes.

[0028] [Step S05] In the subsequent step S05, the worker [W] performs setup operation by operating the operation unit 19 at the landing 100f to adjust the position of the car 10. This operation causes the setup operation control unit 103 in the control device 101 of the elevator 100 to control the drive of the hoist to perform setup operation and move the car 10 to a predetermined height position (step S103). As a result, the boarding determination unit 202 of the remote monitoring device 200 detects (1) the implementation of setup operation (step S104).

[0029] [Step S06] In the next step S06, the worker [W] opens the landing door 17. As a result, the landing door open / close detection unit 18 detects that (2) the landing door 17 has opened (step S105). Subsequently, the boarding determination unit 202 of the remote monitoring device 200 detects that the landing door 17 has opened based on information from the landing door open / close detection unit 18 (step S106). At this time, the elevator car 10 is at a height position that allows the worker [W] on the elevator car to board, and therefore the landing door 17 is not engaged with the elevator car door 12. For this reason, the worker [W] uses the external opening key to open only the landing door 17 in a predetermined procedure. At this time, the worker [W] also opens the landing door 17 wide enough to be able to see inside, and turns on the light 3a attached to the helmet 3 to check the position of the elevator car 10.

[0030] [Step S07] Next, in step S07, the worker [W] operates the on-gauge switch 14 located on the top of the elevator car 10. As a result, the on-gauge switch 14 is operated in the elevator 100 (step S107), and the remote monitoring device 200 (3) detects the operation of the on-gauge switch 14 (step S108).

[0031] As a result of the above, the boarding determination unit 202 of the remote monitoring device 200 detects that it is time for the worker [W] to board the upper part of the car 10 (step S109), and transmits the result to the mobile terminal device 300. At this time, the boarding determination unit 202 determines that it is time for the worker [W] to board the upper part of the car 10 because (1) detection of setup operation, (2) detection of opening of the landing door, and (3) operation of the on-gauge switch 14 have been detected in this order.

[0032] Furthermore, the boarding determination unit 202 extracts the mobile terminal device 300 that is linked to the determined elevator from the elevator / terminal linking unit 201, and transmits the determination result to the extracted mobile terminal device 300. The extracted mobile terminal device 300 is carried by the worker [W] who will perform maintenance work on the determined elevator 100.

[0033] In the mobile terminal device 300 that has received the determination result, the warning issuing instruction unit 303 instructs the issuing unit 301 to issue a warning urging the user to fasten the safety belt hook 2a, and as a result, the issuing unit 301 starts issuing an audio warning (step S110).

[0034] [Step S08] In step S08, after operating the on-gauge switch, the worker [W] fully opens the landing door 17 and gets into the upper part of the car 10 to perform maintenance work. Before or after this action of the worker [W], in step S110, the mobile terminal device 300 starts issuing a warning sound. Therefore, in this step S08, the worker [W] who is about to get into the upper part of the car 10 or who has just gotten into it is prompted to engage the safety belt hook 2a.

[0035] [Step S09] In step S09, the worker [W] who has boarded the upper part of the car 10 is prompted by the warning sound from the alarm unit 301 of the mobile terminal device 300 to fasten the safety belt hook 2a to the fastening portion 15 on the upper part of the car 10.

[0036] [Step S10] In step S10, the worker [W] inputs a warning stop command from the operation unit 302 of the portable terminal device 300 that he / she carries. As a result, the warning stop instruction unit 304 of the portable terminal device 300 causes the warning issuing unit 301 to stop issuing the warning (step S111). Note that step S10 and the previous step S9 may be reversed.

[0037] [Step S11] In step S11, the worker [W] starts maintenance work on the upper part of the car 10, and the process ends.

[0038] <Effects of the first embodiment> According to the first embodiment described above, when the boarding determination unit 202 detects (1) the detection of setup operation, (2) the detection of the opening of the landing door, and (3) the operation of the on-gauge switch 14 in this order, it determines that it is time for the worker [W] to board the upper part of the car 10, and issues an audio warning. Therefore, the mobile terminal device 300 of the worker [W] can issue an alert at the exact timing when the boarding determination unit 202 detects that the worker [W] is boarding the upper part of the car 10. This makes it possible to prompt the worker [W] to engage the safety harness hook 2a with the engaging portion 15 on the car 10 at the most effective timing. As a result, it is possible to support safe maintenance work by preventing forgetting to fasten the safety harness hook 2a during maintenance work on the elevator 100 without requiring any special equipment.

[0039] <Modification of the First Embodiment> <Maintenance work support method> Fig. 4 is a flowchart showing a modified example of the first embodiment. The modified example shown in Fig. 4 differs from the maintenance work support method of the first embodiment described with reference to Fig. 3 in that in step S05', the worker [W] adjusts the position of the car 10 using a procedure other than setup operation. In this case, the worker [W] operates the operation unit 19 outside the car 10 to move the height position of the car 10 to a predetermined position for the worker [W] to get on the car of the car 10. As a result, the control device 101 of the elevator 100 does not perform setup operation, and the remote monitoring device 200 detects that the car position has been adjusted (step S104').

[0040] In this case, the boarding determination unit 202 determines that it is time for the worker [W] to board the upper part of the car 10 because (1') the car position is detected to be adjusted, (2) the hall door is detected to be opened, and (3) the on-gauge switch 14 is operated in this order (step S109').Other than that, the same procedure as in the first embodiment is carried out.

[0041] <Effects of the modified version> Even in the modified example of the first embodiment described above, a warning is issued when the timing at which the worker [W] gets on top of the car 10 is accurately detected, thereby urging the worker to lock the safety belt hook 2a into the locking portion 15 on the car 10 at the most effective timing. Therefore, as in the first embodiment, it is possible to support safe maintenance work by preventing the worker from forgetting to fasten the safety belt hook 2a during maintenance work on the elevator 100 without requiring any special equipment.

[0042] Second Embodiment <System configuration> Fig. 5 is a block diagram of an elevator maintenance work support system 1a according to the second embodiment. The maintenance work support system 1a of the second embodiment shown in Fig. 5 differs from the maintenance work support system 1 of the first embodiment shown in Fig. 2 in the configuration of the mobile terminal device 300, but the other configurations are similar. Therefore, the configuration of the mobile terminal device 300 will be described here.

[0043] [Mobile terminal device 300] The mobile terminal device 300 is owned by the worker [W], and is the same as that described in the first embodiment except that a timer 304a is provided instead of the warning stop instruction unit 304 (see FIG. 2). The timer 304a measures the elapsed time from the point in time when the alarm issuing unit 301 starts issuing a warning. The alarm issuing unit 301 stops issuing the warning when the timer 304a measures that a predetermined elapsed time (for example, 10 seconds) has been reached.

[0044] <Maintenance work support method> Next, an elevator maintenance work support method implemented by the elevator maintenance work support system 1a described above will be described. Fig. 6 is a flowchart of an elevator maintenance work support method according to a second embodiment. The maintenance work support method of the second embodiment shown in Fig. 6 differs from the maintenance work support method of the first embodiment described using Fig. 3 in that in step S08, the worker [W] does not need to perform any operation to stop the warning audio after getting on the car.

[0045] In this case, the process is the same as in the first embodiment up to the point where alarm issuing unit 301 of mobile terminal device 300 starts issuing an audio warning in step S110. Thereafter, in step S101a, timer 304a of mobile terminal device 300 measures the elapsed time from the point where alarm issuing unit 301 was instructed to issue an alarm, and if it is determined that a predetermined elapsed time has been reached (YES), the process proceeds to the next step S111. In step S111, alarm issuing unit 301 stops issuing the warning based on the measurement result of timer 304a.

[0046] <Effects of the second embodiment> The system and method of the second embodiment can also achieve the same effects as the system and method of the first embodiment. Furthermore, the safety of maintenance work can be further improved by eliminating the need for the worker [W] to operate the mobile terminal device 300 to stop the warning sound. The second embodiment can be combined with a modified example of the first embodiment.

[0047] Third Embodiment <System configuration> FIG. 7 is a block diagram of an elevator maintenance work support system 1b according to a third embodiment. The maintenance work support system 1b of the third embodiment shown in FIG. 7 differs from the maintenance work support system 1 of the first embodiment shown in FIG. 2 in that the elevator 100 has a function for issuing a warning to prompt the user to fasten the safety belt hook 2a (see FIG. 1). Therefore, the mobile terminal device 300 does not need to have a warning function, and the configuration of the remote monitoring device 200 may be the same as that of the first embodiment. Therefore, the configurations of the elevator 100 and the mobile terminal device 300 will be described here.

[0048] [Elevator 100] The elevator 100 has a configuration in which an alarm issuing unit 13, an alarm issuing instruction unit 104b, and a timer 105b are added as alarm issuing functions to the elevator 100 of the first embodiment shown in Fig. 2. The alarm issuing unit 13 is the one described with reference to Fig. 1 and may be a speaker installed inside the car 10. The timer 105b and the alarm issuing instruction unit 104b may be components of the control device 101.

[0049] The warning issuance instruction unit 104b instructs the alert issuing unit 13 to issue an audio warning based on a signal from the boarding determination unit 202 of the remote monitoring device 200. The timer 105b measures the elapsed time from the point in time when the warning issuance instruction unit 104b instructs the alert issuing unit 13 to issue an alert based on the signal from the boarding determination unit 202 of the remote monitoring device 200. Furthermore, the alert issuing unit 13 stops issuing the warning when the timer 105b measures that a predetermined elapsed time has been reached.

[0050] [Mobile terminal device 300] The mobile terminal device 300 includes an operation unit 302 and an entry registration function 305. These are similar to those in the maintenance work support system 1 of the first embodiment shown in FIG.

[0051] <Maintenance work support method> Next, an elevator maintenance work support method implemented by the above-described elevator maintenance work support system 1b will be described. FIG. 8 is a flowchart of an elevator maintenance work support method according to a third embodiment. The maintenance work support method of the third embodiment shown in FIG. 8 differs from the maintenance work support method of the first embodiment described using FIG. 3 in that, in step S08, the worker [W] who has boarded the car does not need to perform any operation to stop the warning sound. Also, the elevator 100 has a function for issuing a warning to prompt the worker to fasten the safety belt hook 2a (see FIG. 1), but the other steps are similar.

[0052] In this case, in step S109, the boarding determination unit 202 of the remote monitoring device 200 determines that it is time for the worker [W] to board the upper part of the car 10, and transmits the result to the elevator 100.

[0053] Then, in step S110b, the warning issuing instruction unit 104b of the elevator 100 instructs the alarm issuing unit 13 to issue a warning urging the worker to fasten the safety belt hook 2a, and the alarm issuing unit 13 starts issuing an audio warning. This prompts the worker [W] to fasten the safety belt hook 2a.

[0054] Thereafter, in step S111b, the timer 105b of the elevator 100 measures the elapsed time from the time when the alarm issuing unit 13 was instructed to issue a warning, and if it is determined that a predetermined elapsed time has been reached (YES), the process proceeds to the next step S112b. In step S112b, the alarm issuing unit 13 stops issuing the warning based on the measurement result of the timer 105b.

[0055] <Effects of the third embodiment> The system and method of the third embodiment can also achieve the same effects as the system and method of the first embodiment. Furthermore, the safety of maintenance work can be further improved because the operator [W] does not have to operate the mobile terminal device 300 to issue a warning sound. The third embodiment can be combined with the modified example of the first embodiment.

[0056] Fourth Embodiment <System configuration> Fig. 9 is a block diagram of an elevator maintenance work support system 1c according to a fourth embodiment. The maintenance work support system 1c of the fourth embodiment shown in Fig. 9 differs from the maintenance work support system 1 of the first embodiment shown in Fig. 2 in that the boarding determination unit 202 of the remote monitoring device 200 determines whether a person has boarded the elevator based on a signal from the load sensor 16 of the elevator 100. Since the other configurations are similar, detailed description thereof will be omitted here.

[0057] <Maintenance work support method> Next, an elevator maintenance work support method implemented by the above-described elevator maintenance work support system 1c will be described. Fig. 10 is a flowchart of the elevator maintenance work support method according to a fourth embodiment. The maintenance work support method of the fourth embodiment shown in Fig. 10 differs from the maintenance work support method of the first embodiment described using Fig. 3 in the processing procedure after the worker [W] gets on the car in step S08.

[0058] In this case, in step S08, worker [W] gets on the car, and in step S109c, load sensor 16 of elevator 100 detects that worker [W] has gotten on, and this detection signal is sent to remote monitoring device 200. Then, in the next step S110c, remote monitoring device 200 detects this information.

[0059] As a result, in step S111c, the boarding determination unit 202 of the remote monitoring device 200 determines that the worker [W] has boarded the upper part of the car 10, and transmits the result to the mobile terminal device 300. After that, the mobile terminal device 300 issues an alarm sound in the same procedure as in the first embodiment.

[0060] At this time, the boarding determination unit 202 determines that the worker [W] has boarded the upper part of the car 10 by detecting (1) the detection of setup operation, (2) the detection of the opening of the landing door, (3) the operation of the on-gauge switch 14, and (4) the boarding detection in this order. Note that the boarding determination unit 202 may determine that the boarding of the worker [W] has been detected at the upper part of the car 10 by detecting (1) the detection of setup operation, (2) the detection of the opening of the landing door, and further, either one of (3) the on-gauge switch 14 and (4) the boarding detection in this order.

[0061] <Effects of the Fourth Embodiment> Even in the fourth embodiment described above, if the boarding determination unit 202 detects (1) detection of setup operation, (2) detection of hall door opening, (3) operation of the on-gauge switch 14, and (4) boarding detection by the load sensor in this order, it determines that it is time for the worker [W] to board the upper part of the car 10, and issues an audio warning. Therefore, compared to the first embodiment, the alarm can be issued more reliably when the worker [W] boards the upper part of the car 10, making it possible to prompt the worker to engage the safety belt hook 2a at a more effective timing than in the first embodiment. Note that the fourth embodiment can be combined with the modified example of the first embodiment, the second embodiment, and the third embodiment.

[0062] Fifth Embodiment <System configuration> Fig. 11 is a block diagram of an elevator maintenance work support system 1d according to a fifth embodiment. The maintenance work support system 1d of the fifth embodiment shown in Fig. 11 differs from the maintenance work support system 1 of the first embodiment shown in Fig. 2 in that the mobile terminal device 300 is equipped with a violation warning issuance instruction unit 306d. Therefore, detailed description of components other than the violation warning issuance instruction unit 306d will be omitted here.

[0063] The violation warning issuance instruction unit 306d instructs the issuance unit 301 to issue a violation warning based on a signal from the boarding determination unit 202 of the remote monitoring device 200. The violation warning that the violation warning issuance instruction unit 306d instructs to issue is a warning to warn of a violation of the rules for boarding above the car 10 when performing maintenance work, and to encourage compliance with the rules.

[0064] <Maintenance work support method> Next, an elevator maintenance work support method implemented by the elevator maintenance work support system 1d described above will be described. Fig. 12 is a flowchart of the elevator maintenance work support method according to the fifth embodiment. The maintenance work support method of the fifth embodiment shown in Fig. 12 differs from the maintenance work support method of the first embodiment described using Fig. 3 in the procedure from step S05d onwards by the worker [W]; since the procedures before that are the same as those in the first embodiment, they are not shown in Fig. 12.

[0065] First, in step S05d, the worker [W] adjusts the height position of the car 10 to a position where the worker [W] can get on the car 10. In this case, the worker [W] performs the setup operation described in the first embodiment, or adjusts the position of the car 10 by a procedure other than the setup operation described in the modified example of the first embodiment. As a result, the remote monitoring device 200 detects that the car position has been adjusted by either procedure (step S104d).

[0066] Thereafter, the worker [W] opens the landing door 17 (step S06) and operates the on-gauge switch 14 arranged on the top of the car 10 (step S7) in the same manner as in the procedure described in the first embodiment. As a result, the remote monitoring device 200 (2) detects that the landing door is open (step S106), and then (3) detects that the on-gauge switch 14 is operated (step S108).

[0067] Thereafter, the boarding determination unit 202 of the remote monitoring device 200 determines whether the procedure for boarding the upper part of the car 10 has been performed normally (step S109d). At this time, if the car position adjustment detected in step S104d is an adjustment due to setup operation, the boarding determination unit 202 determines that it is a normal procedure (YES) and transmits that information to the mobile terminal device 300. Thereafter, the process proceeds to step S110 in Fig. 3, and thereafter the procedure described in the first embodiment is performed.

[0068] On the other hand, in step S109d, if the car position adjustment detected in step S104d is an adjustment by a procedure other than setup operation, the boarding determination unit 202 determines that it is not a normal procedure (NO) and transmits that information to the mobile terminal device 300.

[0069] Thereafter, the violation warning issuing instruction unit 306d of the mobile terminal device 300 instructs the issuing unit 301 to issue a violation warning to encourage compliance with the car riding rules, and as a result, the issuing unit 301 starts issuing an audio violation warning (step S110d).

[0070] In step S08d, the worker [W] who has received the audio violation warning inputs a violation warning stop command from the operation unit 302 of the portable terminal device 300 that he or she carries with him or her. As a result, the warning stop instruction unit 304 of the portable terminal device 300 instructs the notification unit 301 to stop issuing the violation warning (step S111d).

[0071] Next, the warning issuing instruction unit 303 of the mobile terminal device 300 instructs the warning issuing unit 301 to issue a warning urging the user to fasten the safety belt hook 2a, and the warning issuing unit 301 then starts issuing a warning sound (step S112d). After that, the same procedure as in the first embodiment is carried out.

[0072] <Effects of the Fifth Embodiment> The system and method of the fifth embodiment can also achieve the same effects as the system and method of the first embodiment. Furthermore, if the procedure for adjusting the car position to get on top of the car 10 does not involve setup operation, a warning is issued for a violation of the rules for getting on top of the car 10, which can encourage the worker [W] to comply with the rules, thereby also improving the safety of maintenance work. Note that the fifth embodiment can be combined with the modified example of the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment.

[0073] The present invention is not limited to the above-described embodiment and modifications, and includes various other modifications. For example, the boarding determination unit 202 may be provided in the control device of the elevator 100. In this case, it is not necessary to provide the elevator / terminal linking unit 201. Furthermore, information may be transmitted from the control device 101 to the remote monitoring device 200 from the elevator 100.

[0074] For example, the above-described embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is also possible to add, delete, or replace part of the configuration of each embodiment with another configuration. [Explanation of symbols]
